Film-coated polyester needle punched felt dust-removing cloth bag film-coated filter material is a composite process of expanded polytetrafluoroethylene (e-PTFE) microporous filter membrane on various substrates (such as polyester felt, PET, PP Textiles, etc.), the laminated filter material not only maintains the inherent high chemical stability, low friction coefficient, high and low temperature resistance, and aging resistance of PTFE, but also resists small particles. Comparable characteristics such as air permeability and water resistance. Is a new type of "breathable membrane filter".
Characteristics of the bag covered with polyester polyester felt precipitator : large air permeability, low resistance, good filtration efficiency, large dust holding capacity, high dust removal rate, filter material for dust removal.
Microfiltration: PET, PP and other non-woven fabrics can be made into filters and filters for chemical, pharmaceutical, electronics and other industries. It can filter micro-particles and isolate bacteria while maintaining high filtration efficiency and low flow resistance. .
Industrial filtration: Polyester felt and PET film can be made into various filter bags, filter cartridges and filters, which are widely used in the treatment and control of smoke and dust particles in industrial fields such as cement, metallurgy, food, coating, petrochemical plastic Recycle.
